Guys, hello everybody!
I am a developer of devices for measuring sound pressure and frequency response in the cabin and related software!
I saw that you are interested in my unit!
That video that you've seen - it is USB BASS METER (Russian name - datcheg-2).
This is a complete single-channel analog TERM-LAB, the error on the TERM-LAB 0.1dB.
Here's our website - www.spl-lab.ru, while translation of a computer, but the site will soon be professionally translated into English, although it can read!
Here's a video with Our parting
